Republican state Rep. Bobby Cleveland told The Oklahoman he is proposing a bill in hopes to stop the deadly game in the state before it starts.

“These kids are attacking people unprovoked in an attempt to knock them out,” Cleveland told The Oklahoman. “They are doing it just for fun. They have been attacking men, women and the elderly. I think we need to send a message that this kind of violence is unacceptable in Oklahoma and will get you into serious trouble.”

Cleveland’s legislation would make sure suspects stay behind bars for a long time as there would be a 10-year minimum prison sentence. The bill would also make sure minors would be charged as adults for the crime.

There have been no known “knockout game” cases in Oklahoma yet.

The deadly game has claimed at least two lives: one in St. Louis and the other one in Hoboken, N.J.

Known “knockout game” cases have also taken place in New York City and Washington, D.C.
